NAME

       cmap_inc - Increase already stored value in CMAP

SYNOPSIS

       #include <corosync/cmap.h>

       cs_error_t cmap_inc (cmap_handle_t handle, const char *key_name);

DESCRIPTION

       The cmap_inc function is used to increase integer value of already stored key inside cmap.
       The handle argument is connection to CMAP database obtained by calling  cmap_initialize(3)
       function.  key_name is name of key to increase value of.

       Function  is  defined only on values where increase makes sense and is well defined, so it
       can be one of:

       CMAP_VALUETYPE_INT8 - 8-bit signed integer

       CMAP_VALUETYPE_UINT8 - 8-bit unsigned integer

       CMAP_VALUETYPE_INT16 - 16-bit signed integer

       CMAP_VALUETYPE_UINT16 - 16-bit unsigned integer

       CMAP_VALUETYPE_INT32 - 32-bit signed integer

       CMAP_VALUETYPE_UINT32 - 32-bit unsigned integer

       CMAP_VALUETYPE_INT64 - 64-bit signed integer

       CMAP_VALUETYPE_UINT64 - 64-bit unsigned integer

       Overflow/underflow is not detected and it's ignored.

RETURN VALUE

       This call returns the CS_OK value if successful. If value  or  key_name  are  unspecified,
       CS_ERR_INVALID_PARAM  is returned. CS_ERR_NOT_EXIST error is returned if key doesn't exist
       (wasn't created by calling cmap_set(3) first).  Some  of  keys  may  be  tagged  read-only
       directly in corosync and setting such key will result in CS_ERR_ACCESS error.
